ATTACHMENT FOR METAL-DRILLING MACHINES.

SPECIFICATION forming part of Letters Patent No. 634,324, dated October3, 1899.

Application filed April l 8 1 89 9.

To all whom it may concern:

Be it known that LWILLIAM E. CANEDY, a citizen of the United States,residing at Chicago Heights, in the county of Cook and State ofIllinois,have invented certain new and useful Improvements inAttachments for Metal- Drilling Machines, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to table-rests and work-clamps for verticaldrilling-machines.

The object of the invention is to improve the support and holder for adrilling-machine, so that various forms of work can be grasped and heldand the position of the work, either on a table or in a clamp, may bereadily ad- -j usted with relation to a drill also, to improve theconstruction of the clamp or vise and the relation of such clamp or viseto the frame of the machine, the table, and the working-tool.

Figure 1 is a perspective view of parts of a drilling-machine, showingimproved clamp in position as a work-table support. Fig. 2 isa'perspective View of clamp or vise in position to grasp arectangularobject, shownin dotted lines, the standard of the drilling-ma chine andthe tool being shown. Fig. 3 is a view similar to Fig. 2, showing clampas ap: plied to a tapering object. Fig. at isa view similar to Fig. 2,showing clamp as applied to a shaft or rod. Fig. 5 is a top plan of theclamp or vise. Fig. Bis a detail elevation of supplementary work-table.

The drilling-machine A, Fig. 1, is of usual construction. Any usual formof upright drill is within the scope of the application of thisinvention, and the illustration, Fig. 1, is intended merely to show therelation of parts, some of the drill-driving mechanism being shown indotted lines.

B denotes the drill-spindle, and C the worktable, both being of usualform.

On the frame of the machine there is an upright cylindrical standard D.On this standard the table-support is vertically adjustable. Thissupport has generally been a bracket-arm, which might be split or not,but was generally held by a set-screw. The part E in the drawingsresembles the usual bracket in respect to its vertical adjustment. Aset-screwF clamps the part E to standard D, and it will be understoodthat this part or (No model.)

bracket may be, adjusted or swung laterally, as well as vertically, onthe standard D as a pivot and support. The part or bracket E is extendedto form one jaw of a vise or clamp. The outer end of the extension isextended upward, as at G, and a vertical notch H in the inner face ofthis jaw forms a holding-receptacle for rods and the like when thedevice is used as a clamp. The upper face of the part G forms either awork-table in itself or a rest for a supplementary table, as will beexplained.

Pivoted at the side of bracket E on a V61 tical pivot is the other jaw Iof the vise or clamp. This jaw I has its upper surface in the plane ofthe upper face of the bracket E, but below the top of G and at a rightangle to the axis of standard D. Instead of afixed extension G the jaw Ihas a pivoted or swivpart of projection G. This pivoted piece or falsejaw K has in its face a notehL, which notch is continued in jaw I as thecounterpart of the notch Hin the other jaw. The false jaw K being freeto turn on its pivot will adapt itself to the form of almost anysubstance placed between the jaws, and when the jaws are drawn togetherby the usual bench-vise screwM engaging the jaws in usual manner thearticle will be firmly clamped between the jaws. The upper surfaces ofextension G and of and may be closed together to form a worktable orspread apart to hold articles between them. The jaws open and closehorizontally. The supplementary table 0, which has a spindle ac, asusual, may enter the notches H H, and the table will then be heldagainst rotation by the tightening of the jaws on the spindle, or thetable may be swung or rotated by leaving the jaws a little loose, withthe table-spindle in the notches.

The lower face of table 0 rests on the up per surface of false jaw K andextension G when the table is applied to the clamp, and as the bracket Eaffords a swivel adjustment of the clamp and table carried thereby it isapparent that the table may be swung to various positions under thedrill and may be rotated or held by means of the clamp, as desirable. Itis also apparent that by removing eled extension-piece K, forming thecounterfalse jaw K are in the same horizontal plane the table C theclamp may be made to hold ening-screw passing through both horizontalvarious forms of material and in adjusted rejaws,allcombinedsubstantially as described.

lation to the drill.

The notches U L are preferably in such relation to the standard D thatthe table 0 when borne on the clamp or vise will naturally center underthe drill unless swung to one side, as explained. This clamp device inits present form is specially intended for use with a verticaldrilling-machine, but is susceptible of other uses without change.

It is well known that there are many known forms of clamps adapted tohold the work under the drill of a drilling-machine. No broad claim ismade herein for the combination of a clamp with such a machine save asthe clamp or vise of this invention has special capacity for such use.The jaws extending horizontally form on their upper surface a table onwhich work may be held, or a further table may be supported thereon, asdescribed.

I claim 1. Thecombination with adrilling-n1achine having an uprightstandard, of a vise or clamp connected to said standard and havingpivoted jaws extending horizontally from such standard, one of said jawsbeing pivoted to the other, and means for closing said jaws inhorizontal direction.

53. The combination with a drilling-machine having an upright standard,of a clamp or vise connected to said standard and having pivoted jawsextending horizontally, one of said jaws having a pivotedextension-piece at its upper face, which extension-piece automaticallyadjusts itself to different forms of material in the jaws, substantiallyas described.

3. In a work clamp or vise attachment for drills, as described, ahorizontally-projecting jaw having an upward extension at its outer end,the upper face of said extension adapted for use either as a work-tableor as a tablesupport, the second jaw pivoted to the first and havingapivoted false jaw corresponding to the extension of the first jaw andcooperatin g therewith to act as a clamp, and a tightt. In a work-clampfor drills as described, the horizontally-projecting jaws pivoted toeach other, the upward extension of one horizontal jaw and the pivotedfalse jaw on the other, both horizontal jaws having a vertical notch andthe false jaw having a notch to correspond therewith, and a tighteningdevice, all combined substantially as described.

5. In adrilling-machine ofthe characterdescribed, the combination of avertical standard, a horizontally-proj ectin g bracket adj ustable onsaid standard and forming one jaw of a vise, a second jaw pivoted to thefirst by a pivot independent of but parallel with the standard, bothjaws having vertical notches in their proximate faces, and havingtightening means by which they may be closed horizontally, and asupplementary table havinga spindle which may enter said notches looselyor be held tightly therein, substantially as described.

6. In a drilling-machine, the vertical cylindrical standard, ahorizontally-projecting jaw which may be swung and vertically adjustedon said standard, a second horizontal jaw pivoted to the first, meansfor closing the jaws horizontally and a pivoted false jaw on the upperedge of one of the horizontal jaws, which pivoted jaw is self-adjustingto the work,all combined substantially as described.

7. In a drilling-machine a vertical standard, a horizontally-projectingarm adj ustably secured to said standard and having an upward projectionforming part of a work-table, a second jaw having upward projectionpivoted to the first independently of the standard and also formingpartof said worktable, and means for opening and closing the jaws inhorizontal direction, all combined substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
